AC Question

So today I was messaging my friend and put the phone down for a second, when I looked at it again I saw the galaxy s3 logo (not the samsung one) , now this has happened to me before and I found answers on google that recommend to push the power button for a few seconds - I tried it back then and it worked.Today it didn't and my battery was at 5% ,I tried to fix it before it died but couldn't.
now the phone is connected to the charger and the screen shows the picture of the empty battery - but it does not charge and disappear and then reappear all the time.
please help..
